With experience, you will discover many additional items to add to the toolkit. Figure 1 shows how a roll of masking tape can be used to label parts that have been removed from a computer when a parts organizer is not available.
A working computer is also a valuable resource to take with you on computer repairs in the field. A working computer can be used to research information, download tools or drivers, and communicate with other technicians.
Figure 2 shows the types of computer replacement parts to include in a toolkit. Make sure that the parts are in good working order before you use them. Using known good components to replace possible bad ones in computers helps you quickly determine which component is not working properly.
